• NB-IoT and LTE-M deployments are proliferating. Proofs of concept abound, but neither technology appears to be generating significant momentum yet.
• Regardless of the technology, moving beyond connectivity is vital to mobile operator success in IoT.
In the past six months, cellular operators worldwide have been rapidly deploying narrowband (NB)-IoT and LTE-M. In June, the GSMA announced the success of its Mobile IoT Initiative, claiming nearly 75 operators deploying NB-IoT or Cat-M and 500 members in its Mobile IoT Innovators initiative designed to help operators add IoT value. The bulk of this focus has been on NB-IoT, which cellular operators are using to establish new use cases, including smart agriculture and a variety of smart cities applications involving lighting, parking meters, smart buildings and the like. For example, T-Mobile USA completed live NB-IoT smart city trials in July 2017 in advance of a planned national launch.
